RVA23 Ends Speculation’s Monopoly in RISC-V CPUs
Summary
RVA23 elevates the RISC-V Vector Extension RVV to mandatory status, redefining how mainstream CPUs scale performance through explicit data-parallelism. The piece argues that structured parallelism can outperform speculative approaches, enabling more predictable performance and energy efficiency, with wide implications for compilers, OS schedulers, and hardware design.
